When players light the beacon near him, players may pass Blaze five logs (the same type that were used to light the beacon) for him to tend the lit beacon with, allowing the beacon to stay lit longer.
Blaze can be spoken to toggle warnings for giving logs to beacon keepers and using logs to light beacons. Additionally, he can provide a brief description of the ring of fire, flame gloves and inferno adze, which are rewarded by King Roald for lighting six, ten and fourteen beacons respectively.
As with some (or all) of the beacon keepers, Blaze has an impulse to deliberately start fires. This behaviour is called pyromania. He becomes quite crazed when he is talking about lighting fire, and this is shown then his animation changes to a wide-eyed expression and he usually screams something about fire, his chathead takes on a unique, deranged appearance.
Blaze still claims that the player is required to redo the lighting of the beacons to reclaim spares of the rewards from King Roald, although King Roald now provides spares of the rewards for free.
